CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority of Chinese Application No. CN202210700943.X, filed on Jun. 20, 2022, the content of which is incorporated herein by reference in its entirety.

BACKGROUND

In various embodiments, the present disclosure generally relates to novel crystalline Forms of heteroaryl compounds, compositions comprising the same, methods of preparing and methods of using the same, e.g., for inhibiting a kinase and/or for treating various diseases or disorders, such as autoimmune diseases described herein.

BACKGROUND

The Janus kinase (JAK) family is a small family of receptor-associated tyrosine kinases that are essential for the signal cascade downstream of type I and type II cytokine receptors. Type I and type II cytokine receptors—which compose a family of receptors bound by over 50 cytokines, interleukins, interferons (IFNs), colony-stimulating factors (CSFs) and hormones—share a distinct intracellular signaling pathway mediated by JAKs that bind directly to the intracellular domains of type I and type II cytokine receptors and not to other classes of cytokine receptor. JAK-dependent cytokines are major contributors to immunopathology. The dependence of type I and type II cytokines on JAKs was established in a variety of genetic models from mutagenized cell lines and knockout mice to humans. Polymorphisms in JAK and signal transducer and activator of transcription (STAT) genes are associated with autoimmunity, and loss of function mutations cause immunodeficiency due to the inability of type I and type II cytokines to transmit signals through their receptors. The critical role of JAKs in type I and type II cytokine signaling strongly argues that interfering with the activity of these kinases could lead to a new class of immunomodulatory drugs.

A new compound and its novel crystalline forms and salts that modulate cytokines and/or interferons, such as IL-12, IL-23 and/or IFNα, should deliver a pharmacological response that favorably treats one or more of the conditions described herein and may provide substantial therapeutic benefits to a wide variety of patients in need thereof.

DETAILED DESCRIPTION

In various embodiments, the present disclosure is directed to Compound 1 or a pharmaceutically acceptable salt thereof or a hydrate or a solvate of the same, which for example, can be in an isolated form, a substantially pure form, and/or in a solid form. As exemplified in the Examples section, various polymorphic forms of Compound 1 were found. Among these polymorphs, Form III of Compound 1 was found to be stable and can be more suitable for various pharmaceutical uses compared to its other forms. Compound 1 has the following molecular formula:

As described in International Application No. PCT/CN2021/140271, filed on Dec. 22, 2021, the content of which is incorporated herein by reference in its entirety, Compound 1 has, as tested in above application, an HEK blue IL23 IC₅₀ value of 2.5 nM, and is advantageous in terms of, for example, human liver microsomal stability, rat pharmacokinetic profiles and selectivity of TYK2 over JAK1, and thus can be useful for treating various diseases or disorders, such as those described herein, e.g., an autoimmune and/or inflammatory disease, such as multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, systemic lupus erythematosus, psoriasis, psoriatic arthritis, Crohn's Disease, Sjogren's syndrome and/or scleroderma.

Compound 1

In some embodiments, the present disclosure is directed to Compound 1 or a pharmaceutically acceptable salt thereof or a hydrate or a solvate of the same. Compound 1 should be understood as in its free form to distinguish it from a salt formed with an external acid or base. Unless obvious from context, Compound 1 should be understood as in its free form as discussed.

Compound 1 can be synthesized by the method as described in International Application No. PCT/CN2021/140271, filed on Dec. 22, 2021, the content of which is incorporated herein by reference in its entirety. The present disclosure provides a modified method for producing Compound 1, comprising the following steps:

-   -   Step 1: Compound 1-1 is reacted with (2,4-dimethoxyphenyl)         methaneamine to produce Compound 1-2;

-   -   Step 2: Compound 1-2 is reacted with cyclopropanecarbonyl         chloride to produce Compound 1-3;

-   -   Step 3: Compound 1-3 is oxidized to produce Compound 1-4;

-   -   Step 4: Compound 1-4 is reacted by removing         (2,4-dimethoxyphenyl) methylene group to produce Compound 1;

Each step in above synthetic method is easy to be carried out and achieves a high yield, thus leading to a total high yield. The resulting product has a high purity of more than 99%, with few impurities. Accordingly, the new synthetic method is suitable for scale-up production.

In some embodiments, Step 1 can be carried out by using cesium fluoride in N-methylpyrrolidone. In some embodiments, Step 2 can be carried out at a temperature of 50-80° C., preferably 60-70° C., and more preferably at 65° C. In some embodiments, Step 3 can be performed by using potassium peroxomonosulfate as an oxidizing agent. In some embodiments, Step 4 can be performed by using an acid, such as trifluoroacetic acid.

In some embodiments, Compound 1 can be in a solid form, such as an amorphous form, a crystalline form, or a combination thereof. In some embodiments, Compound 1 can be an amorphous form. In some embodiments, Compound 1 can be in a crystalline form (e.g., in any one or more crystalline forms I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, or XVII as described herein). As used herein, when Compound 1 is said to exist or be in one particular solid form (e.g., a crystalline form), it should be understood that in some embodiments, the compound can exist predominantly in that particular form. However, in some embodiments, the compound can also exist in the particular form, in a mixture with one or more other solid forms, including amorphous form. For example, when Compound 1 is said to exist or be in Form III, Compound 1 can exist predominantly in Form III, such as more than 80% by weight, more than 90% by weight, or more than 95% by weight of Compound 1 are in Form III, or no other solid form can be identified, for example, by XRPD; or in some embodiments, Compound 1 can exist in Form III, in a mixture with one or more solid forms such as an amorphous form.

Compound 1 herein is typically in a substantially pure form. For example, in some embodiments, Compound 1 can have a purity of greater than 70%, preferably greater than 90% (e.g., greater than 95%, greater than 97%, greater than 98%, greater than 98.5%), by weight, by HPLC area, or both. In some embodiments, the Compound 1 can be characterized by a purity by weight and/or by HPLC area of about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 99%, or any ranges between the specified values. For example, in some embodiments, the Compound 1 can be characterized by a purity by HPLC area of about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 99%, or any ranges between the specified values. The substantially pure Compound 1 can be in a solid form (e.g., a crystalline pure or salt form described herein, amorphous form, or a combination thereof) or in a solution, suspension, or another form. In some embodiments, the substantially pure Compound 1 can be in crystalline Form III. For the avoidance of doubt, a composition comprising the substantially pure Compound 1 herein and one or more other ingredients should be understood as a mixture of the substantially pure Compound 1 herein and the one or more other ingredients, for example, such composition can be obtained directly or indirectly from mixing the substantially pure Compound 1 with the one or more other ingredients, such as solvent, pharmaceutically acceptable excipients, etc.

In some embodiments, the Compound 1 is in a crystalline form. In some embodiments, the Compound 1 is in a crystalline Form I. Characteristics of Form I include any of those described herein. In some embodiments, crystalline Form I can be characterized by (1) an X-ray powder diffraction (XRPD) pattern having one or more (e.g., 2, 4, 6, 8, or 10) of the following peaks: 7.5°, 11.7°, 20.9°, 22.3°, 23.6°, 24.8°, 25.3°, 26.5°, 27.0° and 30.2° (2 theta, ±0.2°); (2) an XRPD pattern substantially the same as shown in FIG. 1 a ; (3) a Differential Scanning Calorimetry (DSC) profile substantially the same as shown in FIG. 1 b ; or any combination thereof (e.g., (1) and (3), or (2) and (3)). In some embodiments, the crystalline Form I can be characterized by an XRPD pattern having the characteristic peaks (e.g., peaks with relative intensity of 5% or above, 10% or above, 15% or above, 20% or above, 30% or above, 40% or above, 50% or above, 60% or above, 70% or above, 80% or above, or 90% or above) of FIG. 1 a or as shown in Table 1 (2 theta, ±0.2°). To be clear, when it is said that the XRPD pattern of Form I has the characteristic peaks of FIG. 1 a or Table 1 or is substantially the same as FIG. 1 a , it does not require that the XRPD pattern have the same relative intensities for the corresponding peaks as shown in FIG. 1 a or Table 1, as applicable. It suffices that the XRPD pattern includes the peaks at the respective diffraction angels (2 theta, ±0.2°) corresponding to the peaks as shown in FIG. 1 a or Table 1, as applicable, regardless of their relative intensities. Similar expressions as to other crystalline forms herein should be understood similarly.

In some embodiments, the Compound 1 is in a crystalline Form II, characterized by (1) an X-ray powder diffraction (XRPD) pattern having one or more (e.g., 2, 4, 6, 8, or 10) of the following peaks: 7.1°, 7.7°, 11.1°, 12.3°, 20.4°, 21.7°, 22.7°, 24.7°, 26.9° and 27.5° (2 theta, ±0.2°); (2) an XRPD pattern substantially the same as shown in FIG. 2 a ; (3) a Differential Scanning Calorimetry (DSC) pattern substantially the same as shown in FIG. 2 b ; or any combination thereof (e.g., (1) and (3), or (2) and (3)).

In some embodiments, the Compound 1 is in a crystalline Form III, characterized by (1) an X-ray powder diffraction (XRPD) pattern having one or more (e.g., 2, 4, 6, 8, or 10) of the following peaks: 7.0°, 9.7°, 14.1°, 14.5°, 17.2°, 18.2°, 19.6°, 21.3°, 24.1°, and 27.0° (2 theta, ±0.2°); (2) an XRPD pattern substantially the same as shown in FIG. 3 a ; (3) a Differential Scanning Calorimetry (DSC) pattern substantially the same as shown in FIG. 3 b ; or any combination thereof (e.g., (1) and (3), or (2) and (3)).

In some embodiments, the crystalline Form III of Compound 1 may be obtained by slurrying the crystalline Form I in acetone, preferably in acetone at 35-75° C. for 1 hour to 2 days. Alternatively, the crystalline Form III of Compound 1 can be obtained by first slurrying Compound 1 in tetrahydrofuran, and then slurrying in ethanol and water. Preferably, the crystalline Form III is obtained by first slurrying in tetrahydrofuran at 55-75° C. for 0.5 to 5 hours, and then in ethanol and water at 60-80° C. for 6 to 48 h.

Above all, 17 crystalline forms of Compound 1 in free form were obtained and characterized, wherein Forms I, II, III, IV, V, VIII, X, XIII, XIV, XV and XVI were anhydrates, Forms VI (di-hydrate) and VII (channel hydrate) were hydrates, and Forms IX, XI, XII and XVII are solvates. Besides, 11 crystalline salts of Compound 1 with different forms were obtained, including sulfate, phosphate, besylate, mesylate, potassium salt and choline salt.

Inter-conversion study among identified anhydrates (Form I, Form II, Form III, Form IV, Form V, Form VIII, Form X, Form XIII, Form XIV, Form XV) was conducted in different organic solvents between RT to 60° C. Results suggests Form III is the most stable anhydrate form between RT to 60° C.

The slurry bridging studies among Form I, Form III and Form VI under different water activities was performed to identify the critical water activity under both 25° C. and 50° C. Result shows Form III is more stable when the water activity is not more than 0.56 at 25° C. and 0.83 at 50° C., respectively.

Solubility of Form III is low and pH-dependent with higher solubility observed in Simulated Gastric Fluid (SGF). Solid stability result showed Form III was physically and chemically stable at 40° C./75% RH and 60° C. for 7 days, and the crystal form remained unchanged at 92.5% RH for 10 days. Physical properties of the lead form are presented in Table 28.
